If he’d only played on and cowritten “Green Onions,” keyboardist Booker T. Jones still would be a legend, as that’s one of the few songs that can be classified as perfect. Obviously, Jones has done tons of tremendous work since that 1962 smash, both with Stax house band the M.G.s and solo. The 68-year-old has cut three albums in the last four years, all with more spry, edgy funk than you’d expect from a sexagenarian. He’ll be supporting 2013’s Sound the Alarm tonight.
